intelligence official tells the cnn that the fbi informed the director of national intelligence james clapper about the investigation on tuesday night, election night, just as some polls were beginning to close and director clapper as a friending colleague, fellow officer, and admirer, urged petraeus to step down from his position. we know as well from that intelligence source that director clapper informed the white house on wednesday and then, of course, the president and general petraeus met and that's when, in fact, his resignation was offered to the president. the questions now will, of course, focus on the second woman. who was she? what was the nature of her relationship with petraeus and what more do the officials know about the e-mails and this other woman? maybe some of the questions will be answered as the oversight committee now begin to pose questions of their own in this investigation and why they weren't informed of it until just hours before general petraeus sent notice of his resignation and the reasons behind it to the men and women behind the cia. >>> michael hayden
